Answer:
mkdir -p /path/{projectFiles/{source, data, results}}

- mkdir is the command for creating directory in unix shell
- -p is used for creating several subdirectories at the same time
- /path/ after, the path is given for the directory projectFiles
- {projectFiles/{source, data, results}} is followed after the path as the directory and subdirectories to be created in curly brackets.
